Can I count even though I'm not an author? I'm still hunting for something easy-to-use to make more of my technical and personal materials kindle-ready. (Does this let me edit, too? Or straight conversion from one format to another?)

Oh yes, a world of yes - a lot of the epub editors/converters I've tried pretend they can do the odd formatting I sometimes use, but then it disappears in iBooks & Stanza - I can get Sigil to do it, but then trying to get a pdf turns into a gigantic pain with a bunch of other software. I crave a single application that can pop out all the formats I need in one nice, clean workflow. :-D
